i have a 92 acura integra gs that has started to bog and misfire between 1000-3000rpm,just after i installed a short ram intake. and the problem has consisted even after i reattached the stock one. i do believe i hooked up all the vacuum lines and pcv tube correctly.it has the standard non vtec b18a1 engine. any help would be much appreciatedthankyou

do you think u might of messed with your air-flow sensor when you installed ur intake? id take a look at it.

not sure but you could have damaged one of the air intake sensors . try and reset the ecu and see if that helps. it may just be coincidental .

if you put the stock intake back in it could be ur timing is off

hahahaha I like how someone said your timing could be off cause of the intake hahaha anyways it may not even have anything to do with the intake unless you... got water on the intake when you washed the motor or filteror your vacuum line has a leak

unplug the ecu main power for a few minutes, reconnect it and turn the car on. do not step on the gas. just let it idle and the ecu should reconfigure the air fuel ratio back to stock setting. you rpm needle will bounce up and down for a while. it should settle down at 750-780rpm. if it doesn't then their is a vacuum leak or idle sensor failure. for that year of integras, the bogging and rough idling is usually cause by the hot water idle sensors on the back of the intake manifold or the one just right underneath the throttle body. pull those off and clean out the hard water deposit build up in there and it should be fine again.
